PACKAGING OF RAZOR BLADES Filed Jan. 25, 1941 2 Sheets-Sheet 2 Patented June 15, 1943 PACKAGING 0F RAZOR BLADES Noel Pemberton Billing, Kingston-on-Thames, England Application January 25, 1941, Serial No. 375,965 In Great Britain February 1, 1940 1 Claim.

This invention consists in improvements in or relating to the packaging of razor blades of the safety type, which blades are thin and flexible.

Generally such blades are greased and then wrapped in greaseproof paper over whichan outer envelope is usually provided. Before a blade can be used it is necessary to unwrap the paper covers which generally is inconvenient owing to the adherence of the inner cover to the greased blade.

An object of the present invention is to obviate the necessity for such wrappin and to provide a package of greased razor blades which will be readily accessible to the user.

According to the present invention, a package for razor blades of the type in question comprises a magazine containing a number of such blades and a sliding tray in the magazine by means of which one blade at a time can be ex-. tracted by moving the tray out and in.

Preferably, there is combined with the magazine, either secured to the sliding tray or formed as part of a wall of the magazine or attached thereto, a magnet or magnets whereby the edges of the blades will be magnetically treated or at at least the edge of the lowermost blad will be so treated.

In one example of the invention there may be secured to the lid of the package or there may be placed immediately beneath it and above the charge of blades an absorbent pad charged with oil so that the blades in the magazine are always maintained in an oily waterproof condition.

A preferred example of the invention will now be described with the aid of the accompanying drawings, in which- Figure l is a plan of the package showing the lid raised;

Figure 2 is a section on the line 2--2 of Figure 1, looking in the direction of the arrows;

Figure 3 is a section on the line 3-3 of Figure 1, looking in the direction of the arrows;

Figure 4 is a plan of the package showing the lid closed and the sliding tray withdrawn, and

Figur 5 is a section similar to Figure 2 showing a modified form of the invention but with the lid closed and the sliding tray withdrawn.

Like reference numerals indicate like parts in the several figures of the drawings.

The body of the magazine In is of rectangular form and is hollowed out and machined internally to afford a shaped recess I I to accommodate the blades I2 and also to afford a lower compartment, beneath the space normally occupied by the blades, in which is received the sliding tray II. The latter compartment extends from the back wall IA of the body of the package completely through the opposite wall thereof, thus affording a slot in the latter wall for the free movement of the tray. The tray itself is formed with ears I5 which constitute abutments to limit the inward movement of the tray and also to afford finger-grips by which the tray can be manipulated.

Hinged to the back wall II is a lid I6 which is recessed on its inner face to receive in the recess an absorbent pad II. The pad is intended to be charged with oil and when the lid is closed this oiled pad will press down on to the blade contents of the package so that the blades will also be maintained in an oily condition. A stud-headed projection I 8 extending inwardly from the lid will, when the lid is closed, be located in a recess I9. Penetrating into the recess through a lateral slot is a plunger 20 urged inwardly by a compression spring 3|, the latter being retained in position by means of a grub screw 22 which also closes the end of the lateral slot, which latter is formed inwardly from the outer surface of the side wall of the body III as clearly shown in Figure 1. The spring plunger 2! acts as a snap catch to engage beneath the stud head I I, when the lid is closed.

On both sides of the tray longitudinal recesses 23 are provided and in each such recess there is situated, and secured against accidental removal, a bar magnet 24. As shown most clearly in Figure 3, these magnets are located beneath the cutting edges of the blades.

The inner end of the tray is also formed with two longitudinal slots 25 and these slots slide over pins 26 upstanding from the base of the package and secured therein'as clearly indicated in Figure 2. The floor of the tray is machined with a shallow recess 21, the depth of this recess being approximately the thickness of a blade and the pins 28 project to a height beyond the base of recess 21 to an extent substantially equal to the depth of this recess. Thus, the complete pile of blades I2 is slightly tilted to facilitate and ensure that only the bottom blade will be removed when the tray I8 is withdrawn, this removal being effected by means of a pin 28 which stands up above the floor of recess 21 and is secured in the tray near its forward end at a position to engage within one of the usual slots provided in blades of this nature. The height to which pin 28 stands above the floor of recess 21 is approximately equal to the thickness of one blade, or even slightly less, thus ensuring that only one blade at a time will be removed at each other locating pins 29, in addition to pin 2|, may be provided to engage with certain portions of the slot such as is formed centrally and longitudinally in blades of the type in question.

In the further modification illustrated in Figure 5, to replace pins 26, which prevent the rear ends of the blades falling into the tray compartment when the tray is withdrawn, a spring 30 is provided secured to the bottom of the package at 3| in a recess shaped to receive the spring so that when the tray is again moved inwardly the spring is accommodated beneath the tray without interfering with its movements. Furthermore, to ensure the blades being fed downwardly on to the tray a bow spring 32 secured at one end at 33 to the inner surface of the lid may be employed also accommodated in a recess in the lid. Springs such as Ill and 32 may be provided along opposite sides but Figure 5 illustrates both examples.

It will be seen, particularly in Figure 1, that the upper space in which the charge of blades is received is specially shaped to fit the blades, but it is to be understood that the shaping shown may be varied to suit any particular requirements.

Moreover, if the body illustrated in Figure 4 is I assumed to be formed with a lid which is not hinged or removable, and therefore may be in one piece with the rest of the body. the invention includes such a modification, but in this case the blades will have to be inserted before the lid or cover is applied to the body and when the last blade has been extracted the package will require to be discarded.

When a hinged lid is utilised, as is preferred, the blades can be used over and over again. For instance, after a blade has been used it will be cleaned and dried in the usual way and replaced on the top of the blades in the package where it will receive a rest for a period of time corresponding to the number of blades which can be charged into the package or which are normally desired to be contained therein. Under these conditions, after a blade has been once used and before it need be called into use again both its cut-- .ting edges will have received beneficial treatment from the magnetic fields provided by the bar manipulation of the tray, that blade being the bottom blade. In the modification illustrated in Figure 4-;

magnets 24. It is found by this means that the cutting edges are maintained clean and bright g for a considerable period of time and the wastage of blades may, therefore, be considerably reduced.

This saving is also aided by the presence of the oil-containing pad I! by means of which the blades are always maintained in an oily condition.

The use of additional pins such a 29 serves to prevent the blade from any chance swinging on the tray and thus ensures any accidental scraping of its cutting edge along any part of the box as the blade is being withdrawn by removal of the drawer.

The lids, and in fact the whole package, may be made more decorative, if desired, than in the example illustrated and the removable lid may be made removable in other ways than by hinging as will be understood without further illustration; and, furthermore, the lid can be locked in position by any other preferred means than those illustrated in the drawings.

The magnet is also a primary or additional means of ensuring the adhesion of the blade to the drawer and thereby assuring its location for withdrawal. It also ensures that in the event of the top pressure being inoperative owing to some blades having been removed, the bottom blade will always be attached to the withdrawal member.

I claim:

A razor blade package comprising a container shaped as to its upper part to afford a recess to receive a number of thin fiat blades piled one on the other and below that space a compartment to receive a sliding tray, a sliding tray therein, bar magnets secured in the tray with their axes parallel to the direction of movement and located near opposite sides of the tray so as to lie beneath cutting edges of the pile of blades when charged into the package, a hinged cover, an absorbent oil-carrying pad securedto the cover so as to overlie the pile of blades when the cover is closed, locating pins extending across the tray compartment to support. the rear edges of the blades, a

recess in the blade-receiving surface of the tray to accommodate one blade and a pin on the tray to engage the lowermost blade near its forward end.
